HELP!!! truck wont turn

[99PSD-White]

Yesterday my truck started acting really werid when backing up into a parking spot. My truck was so hard to turn the wheel when stopped, I know its on 37s but it was way harder than usual like it acts there is no power steering. Also the brake pedal got really soft and when u hit the brakes it pretty much would lock up the tires. Checked the fluid which was a little low so i put some more in and nothing. Backing out of the driveway this morning I could barly turn to drive my truck down the street. I need some help here guys!

Power steering pump bad?

I know how that is, my P/S pump is on it's way out, and it can be a chore to turn the wheel in slow/stopped maneuvers. I also notice the fact I have pulsation in the pedal and lose steering power when the brakes are applied hard. (My rotors are warped, I know what that feels like)

These trucks use the Power Steering pump to steer the truck and boost the brakes, as diesels do not create vacuum to operate a booster like a gasoline car. For a quick fix you could always try a flush and see if that helps, or just bite the bullet and get it replaced.

They are a bit of a pain to DIY, as the pulley has to be pulled off and pressed on to remove it from the bracket. Not impossible, but an annoyance.

thanks guys for the help. The pump is only 50 bucks so that aint bad.

well i replaced the pump and still the same thing. I think im going to get a new steering gear box tomorrow under warranty. This will be my 3 box in 3 years. While the box is out ill truck the wheel to flush the fluid and put new in when i put the new box in. Any other ideas what could be wrong?
